Choline is vital if you are to successfully increase and maintain your intelligence at astronomical levels. You don’t necessarily have to take a supplement because the best sources are actually in egg yolks, peanuts, milk liver, fish, broccoli, cabbage and cauliflower. Brain Plus IQ Egg yolk is the ultimate source but it has been exonerated due to their high cholesterol content. I think this is ill-founded since new research shows that high cholesterol is caused more by saturated fat and genetics.Nevertheless, in dosage terms, men and lactating women need 550mg of choline per day whilst women and pregnant women need between 425-450mg. In supplement form, lecithin is the way to go, though choline by itself is also acceptable. A tablespoon of lecithin granules supplies about 250mg of choline. http://israelbigmarket.com/brain-plus-iq/
